AXLE-LUBRIGATOR.

Specification of Letters Patent.

Patented Feb. 9, 1909.

Application filed April 13, 1908. Serial No. 426,798.

To all whom it may concern:

Be it known that I, LOWELL E. SHERWOOD, citizen of the United. States,residing at Chelan, in the county of Chelan and citate of Washington,have invented certain new and useful Improvements in Axle Lubricators,of which the following is a specification.

The present invention relates to an improved axle lubricator embodyingnovel means for supplying the .axle with lubricant from a reservoirpermanently mounted thereon.

The object of the invention is the provision of a simple and inexpensivelubricating device of this character which will prevent loss or waste ofthe lubricant and when applied to a vehicle will eliminate the necessityfor removing the wheel when it is desired to grease the axle.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction and the meansfor effecting the result, reference is to be had to the followingdescription and accompanying drawings, in which Figure 1 is aperspective view showing the lubricating device applied to a vehicleaxle. Fig. 2 is a detail View of the removableaxle spindle. Fig. 3 is asimilar view of one end of the axle tree to which the spindle isattached. Fig. 4 is a top plan view of the device. Fig. 5 is a sectionalview on the line 55 of Fig. 4. Fig. 6 is a transverse sec-' tional viewon the line 66 of Fig. 1. Fig. 7 is a longitudinal sectional viewthrough the cup which is applied to the reservoir. Corresponding andlike parts are referred to in the following description and indicated inall the views of the drawingsby the same reference characters.

Referring to the drawings, the numeral 1 designates an axle and-2 aspindle which is detaehably applied to the axle, the inner end of thespindle being formed with an extension 3 received with n a correspondingrecess at the lower portion of the axle. It will also be observed that ashoulder i is formed at the base of the extension 8 and abuts againstthe end of the axle in the usual manner. A tongue 5 is also shown asprojecting longitudinally from the end of the axle and received withinthe spindle.

Extending within the spindle 2 from the shoulder 4 is thelongitudinal'p'assag'e 6 communicating at its inner end with a lateralopening 7 leading to the top of the spindle. A tube 8 is fitted withinthe longitudinal passage 6 and has a threaded connection toward itsinner end with an upwardly extending feed tube 9 adapted to lead thelubricant from the longitudinal tube 8 to the exterior of the spindle 2.In the preferred embodiment of the invention this longitudinal tube 8 isthreaded in position within the passage 6 and is provided at its outerend with an angular socket 8" designed to engage any suitable tool forscrewing the tube in position or removing it therefrom. It will also beobserved that the rear end of the tube 8 projects beyond the shoulder atand is received within a recess in the axle 1.

A supply tube 10 has a threaded connection with the tube 8 toward therear end thereof, and this supply tube is located at the junction of theaxle and spindle and is received within corresponding depressions formedin the shoulder 4 of the spindle and the abutting end of the axle. Thissupply tube projects upon one side of the axle and is threaded into oneend of a reservoir 11 which is permanently clamped upon the exterior ofthe axle. Interposed between this reservoir and the axle is a fillingblock 12 which is perforated to receive the supply tube 10 and has theinner face thereof recessed so as to fit over the rounded portion of theaxle.

The clamp for holding the reservoir 11 in position may be of anyapproved construction and in the present instance is shown as formed bya U-shaped band 13 fitting over the reservoir, the arms of the bandembracing the top and bottom of the axle and terminating in threadedstems which pass through openings in a cross bar 14: and are capped bythe nuts 15. It will thus be obvious that by tightening the nuts the U-shaped band 18 may be caused to clamp the .reservoir securely inposition upon the axle.

The open end of the reservoir 11 receives a removable cup 16, which hasa tubular formation and'constitutes an extension of the reservoir, themouth of the cup being threaded within the reservoir and a set screw 17being utilized for locking the cup against loss or accidentaldisplacement. A follower 18 is mounted within the cup 16 for the purposeof forcing the lubricant therefrom, the said follower being held againstrotation within the cup and having a threaded'connection with a stem 19passing longitudinally through the cup. This stem is journaled withinone end of the cup so as to rotate freely and at the same time be heldagainst longitudinal movement and terminates in an angular stud 19designed to receive a. removable handle 20.

When it is desired to supply the device with lubricant the cup 16 isdetached from the reservoir and the follower l8 mo'ved to the rear endof the cup. The lubricant is then placed within the cup and the lattermember again threaded in position upon the reservoir. By applying thehandle 20 to the angular stud 19 of the stem 19 the said stem can beturned to move the follower out.- wardly and force the lubricant fromthe reservoir through the tubes 10, S and 9 to the exterior of thespindle :2. The quantity of lubricant supplied to the wheel can beestimated according to the number of turns imparted to the stem 19, andlubricant can be readily supplied to the spindle at any time without thenecessity of removing the wheel therefrom.

Having thus described the invention, what is claimed as new is:

1. The combination of an axle, a spindle detachably applied to the axleand formed with a shoulder abutting against the end of the axle, areservoir carried by the axle, a supply tube fitted between the shoulderof the spindle and the end of the axle and leading from the reservoir,and means for taking lubricant from the supply tubeand carrying it tothe exterior of the spindle.

2. The combination of an axle, a spindle detachably applied to the axleand formed with a shoulder abutting against an end of the axle, the saidspindle being also termed with a longitudinal opening extendinginwardly-from the shoulder and communicating with a lateral opening leading tothe exterior of the spindle, a reservoir carried by the axle, and asupply tube titted between the shoulder of the spindle and. the end ofthe axle and communicating between the reservoir and the longitudinalopening of the spindle.

The combination of an axle, a. spindle detachably applied to the axleand formed with a shoulder abutting against an end (it the axle, thesaid spindle being also ,tornied with a lon itudinal opening extendinginardly from the shoulder and coninniniuding at its inner end with alateral opening leading to the exterior ol. the spindle, a tube thread1d within the longitrulinal opening in the sp ndle, one end ol the tubeprojecting beyond the shoulder for engagement with a tool when placingthe tube in position or removing it therefrom, a teed tube communicatingwith the before mentioned tube and arramged within the lateral openingof the spindle, a supply tube detachably connected to the rear end ofthe longitudinal tube and arranged between the shoulder ol the spindleand the end of the axle, and a reservoir can ried by the axle andcon'innuiieating with the supply tube.
